Postgres function input parameter as TEXT Array problem - postgresql

Question

My Table looks like
CREATE TABLE dev.clbk_logs
(
id bigint NOT NULL,
clbk_typ character varying(255) COLLATE pg_catalog."default",
clbk_json json,
cre_dte timestamp without time zone,
ld_id bigint,
ld_num character varying(255) COLLATE pg_catalog."default",
mod_dte timestamp without time zone,
CONSTRAINT clbk_logs_pkey PRIMARY KEY (id)
)
WITH (
OIDS = FALSE
)
TABLESPACE pg_default;
My function is
CREATE OR REPLACE FUNCTION dev.my_method(p_callback_types TEXT[], p_days_ago INT)
RETURNS SETOF dev.clbk_logs
LANGUAGE 'plpgsql'
AS $BODY$
BEGIN
return query
SELECT * FROM dev.clbk_logs
WHERE (clbk_Typ::TEXT) IN (($1)) AND (current_date - cre_dte::date)< p_days_ago;
END;
$BODY
Can someone please help what is wrong in above, and should make expected result.
I wanted to pass an array of string and in query.
Error I am getting is
LINE 2: WHERE (clbk_Typ::TEXT) IN (($1)) AND (current_date - cre_...

HINT: No operator matches the given name and argument types. You might need to add explicit type casts.
QUERY: SELECT * FROM dev.clbk_logs
WHERE (clbk_Typ::TEXT) IN (($1)) AND (current_date - cre_dte::date)< p_days_ago
CONTEXT: PL/pgSQL function dev.my_method(text[],integer) line 3 at RETURN QUERY

You need to use = any() not IN with an array.
The cast to ::text is also not needed. And for readability I would recommend using the parameter name, rather than the number:
CREATE OR REPLACE FUNCTION dev.my_method(p_callback_types TEXT[], p_days_ago INT)
RETURNS SETOF dev.fourkites_clbk_logs
LANGUAGE plpgsql
AS $BODY$
BEGIN
return query
SELECT *
FROM dev.fourkites_clbk_logs
WHERE clbk_Typ = any (p_callback_type)
AND (current_date - cre_dte::date) < p_days_ago;
END;
$BODY
Note that your condition on cre_dte can't use an index if you ever create one. If you want that condition to be able to use an index, change it to:
and cre_dte >= current_date - p_days_ago;
